CORPORATION OF FLY FRAME.

Applicationlfiled January, 24,1929. Serial No. 334,643.

The invention has relation to the covers which, in a fly-frame employed in the manufacture of rovings in the process of spinning, are located between the front row of spindles and the back row thereof, to close the interval or space between the two rows. Customarily,'a set of such covers is provided above and adjacent the spindle-driving gearing,and a second set thereof is provided aboveand adjacent the bobbin-driving gearing. Marginal notches are provided in these covers for: occupancy by the spindles in the case of the lower set of covers, and in the case of the upper set of covers by the sleeves of the bobbin gears, in orderthat portions of the covers may extend between the spindles of each row so as to close the opening between one spindle and the next in the case ofeach row.

One object of, the invention is to permit a are made in the said intermediate covers to accommodate the spindles and the sleeves of the bobbin-gears, in order, by such reduction of the size of the openings occupied by the spindles and sleeves, respectively, to lessen the opportunity for passage of lint, &c., down through to the said gearing. Another object is to improve the construction of the said intermediate covers. I

The features of the invention are explained in the following description, with reference to the illustrative embodiment of the same in the organization of a roving frame, otherwise known as a fly-frame, and are particularly pointed out in the claims at the close of this specification.

Fig. 13 is a plan View on such scale of a of the machine to the other, in which the spindles 1, 2, of a fly-frame are arranged, are 7 indicated in Figs. 1, 2, and 3. The said views indicate also the quincunxial or staggered disposition which locates a spindle of one row opposite a space between two spindles of the other row, and so on in succession. Figs. 1 and 2 show the spindles mounted as usual in steps 3 carried by a step-rail 4:, and in bolsters 5 carried by a bolster-rail 6. Fig. 1 shows fliers 7, 7, carried by the spindles, as usual, and bobbins 8, 8, concentric with the upper portions of the spindles and having loads 9, 9, of rovings wound thereon. Spindle driving gearing of usual character is shown,

, of the bobbins and with the bolster-rail 6. The said spindle-driving gearing includes the bevel'pinions 10, 10, which are secured upon the lower ends or feet of the spindles, the driving bevel-gears 100, 100, and the shafts 101,101,'e'xtending longitudinally of the machine, upon which the said bevel-gears are mounted and the'bobbimdriving gearing includes the bevel bobbin-gears 11, 11, the driving bevel-gears 110, 110, and the shafts 110, 110-, extending longitudinally of the machine. The bobbin-gears 11, 11, as usual, are mounted upon the exteriors of the bolsters 5 and free to turn thereon, and are furnished with upwardly-extending sleeves or hubs 112, 112, which engage with the bobbins so as to cause the latter to turn in unison with the bobbin-gears. At 12 and 120 are the usual longitudinally extending curved cover-plates which shield and partly enclose the two sets of driving-gearing at front and rear, respectively, of the two ranks of spindles. These cover-plates 12, 120, are as usual removably mounted upon the cover-plate suppdrting stands to which reference is made later here- Having reference, now, to the parts and features involved in the invention,

At 13, 14, are the intermediate covers, which will be described later herein. As indicated previously herein, there is a lower set of these covers adjacent the spindle-driving gearing, and an upper set thereof adjacent the bobbin-driving gearing. At 15, 15, are cover-supporting stands which are mounted upon the step-rail 4 at intervals apart, so that sectional groups of spindles intervene between successive stands; and at 16, 16, are cover-supporting stands which are mounted upon the bolster-rail 6 at similar intervals. The various covers are suported by their ends resting upon the tops of these stands. One of the step-rail-stands 15 is shown detached in Figs. 4 to 7; and one of the bolster-railstands 16 is shown detached in Figs. 8, 9, 10.

; These stands respectively extend from front to rearbetween spindles, or bobbin-gear sleeves, of the two rows. Their endportions project at front and rear, respectively, of the two rows, for the reception of the front and rear curved cover-plates 12 and 120. A characteristic feature which in a certain sense underlies the present invention is the diagonal or oblique direction of the intermediate portion of each of these stands which is'necessitated by the quincunxial relationship of the spindles of the two rows or ranks, by reason of which a spindle of the back row or rank is opposite a space between spindles of the front row, and vice versa, as indicated in Figs. 2 and 3. In virtue of a stand being formed with a diagonal or oblique intermediate portion, the rear portion of the stand, such portion serving for the support of the back curved cover 120, occupies the space between two spindles of the back row of spindles, in a. position in which such' portion of the stand is clear of the said spindles, or of the bobbingear sleeves, and the front portion, of the stand, such portion serving for the support of the front curved cover 12, occupies a space between two spindles of the front row which is offset laterally with relation to said rear space, and likewise. in a position in which such portion of the stand is clear of the spindles or obbin-gears between which it projects.

Figs. 4 to 10 show the preferred construction of the stands'15, 16, each thereof being provided with a diagonal or transversely oblique intermediate portion, and with the two end-portions. of each stand laterally offset with relation to each other. vAs shown best in Figs. 1 to 10, an upstanding rib 151 or 161 extendslongitudinally of each stand, intermediately of the width of the cover-supporting parts thereof; and cover-sustaining ledges 152, 152, or 162, 162, are located at opposite sides of the said upstanding rib. The ends of the cover-members rest upon the said ledges, alongside the upstanding rib, and the said extremities are beveled at anangle conforming to thatof the rib. It will be seen that the up the same section of spindles. The front mem ber of a pair hasin the front edge thereof notches as 121, 121, Figs. 11 and 13, foroccupancy by the spindles of the front row or rank of such section, or by the sleeves of the bobbin-gears pertaining to such spindles, as the case maybe. The back edge of the rear IDQIllber of the pair has therein notches, as 14:1, 14:1, Figs. 11 and 13, for occupancy by the spindles of the back row or rank of such section, or by the sleeves of the bobbin-gears pertaining to such spindles, as the case may be. The marginal portions intermediate the notches extend between the spindles and into close proximity to the inner margins of the front and back cover-members 12, 120.

The operation of placing an intermediate cover-member in working position upon two of the cover-supporting stands is performed by introducing such cover-member between the two rows orranlrs of spindles, and, with the'extremity of the cover-members guided by the upstanding ribs of the supporting stands, then sliding the cover-member edgewi-se, notched edge leading, toward the. appropriate row or rank, until the margin of such edge has brought up against the inner edge of the. corresponding curved covermember, with the notches occupied by the spindles of such row or rank, or the bobbingear sleeves in connection with such spindles.

It will be apparent, (see Fig. 3), that as an intermediate cover-member is slid toward the row or rank of spindles with which it is bobbin-gear-sleeves, in effecting application or removal of the nitermediate cover-mem bers, I form the respective notches in the margins of the latter with the lateral sides thereof corresponding oblique or diagonal and parallel with the diagonal ribs. This feature enables the said notches to be made just wide enough to accommodate a spindle or a bobbin-gear-sleeve without contact between the notch-margin and the spindle or sleeve, and without interference with the application and removal of the intermediate covers. Consequently, opportunity for lint, &c., to sift down around the spindle or sleeve through the notch, to reach the drivingegear, is minimized.

Figs. 1 and 11 to 13 show intermediate cover-members composed of thin sheet-like material, and having down-turned longitudinal margins. The said cover-members are supported in working position by the edges of these down-turned flanges resting upon the lateral ledges 152 and 162 of the coversupporting stands. The flanges give strength to the cover-members. They stiffen the latter. They provide against warping and bending thereof. They broaden the edges of the cover-members. This has an advantage in that the contact of the vertically-broadened flanged rear edge of the front cover-member of a pair thereof with the vertically-broadened flanged front edge of the rear cover member of the pair prevents overlapping of the meeting edges. The shoulders at the longitudinal bends are rounded, as in Fig. 12, and thereby roughness against which fly, &c., might lodge is eliminated, so that the operation of wiping fly, dirt, .and other foreign matter, from the cover-members is facilitated. The two intermediate cover-members preferably are made of sheet materials, with the marginal flanges produced by bending; they may, however, be cast intheir final form.

What is claimed as the invention is 1. In a fly-frame having spindles in two rows or ranks arranged in a quincunxial formation and cover-supporting stands intersecting said rows or ranks at intervals between sectional groups of spindles, with such stands extending from front to rear diagonally or obliquely from a space between spindles of the front row to a laterally-offset space in the back row, and with the said stands provided with diagonal or oblique end-guides for intermediate covers, the combination with such stands, of intermediate covers for gearing that is associated with the spindles, engaging by their ends with said end-guides, guided thereby in being inserted into place, and having correspondingly diagonal or oblique notches for occupancy by the spindles.

2. In a fly-frame having spindles in two rows or ranks arranged in a quincunxial formation, and cover-supporting stands intersecting said rows or ranks at intervals between sectional groups of spindles, with such stands extending from front to rear diagonally or obliquely from a space between spindles of the front row to a laterally-offset space in the back row, and with the stands provided with cover-supporting ledges alongside diagonal or oblique upstanding guide-ribs, the combination with such stands, of intermediate covers for the gearing that is associated with the spindles, supported by resting by their ends upon the said ledges, and positioned endwise through engaging with the said ribs, the said intermediate covers having correspondingly diagonal or oblique notches for occupancy by the spindles.

3. In a fly-frame having spindles in two rows or ranks arranged in a quincunxial formation, and cover-supporting stands intersecting said rows or ranks at intervals betweensectional groups of spindles, with such stands extending from front to rear diagonally or obliquely from a space between spindles of the front row to a laterally-offset space in the back row, and with the stands provided with cover-supporting ledges alongside diagonal or oblique upstanding guideribs,-the combination with such stands of intermediate covers for the gearing that is associated with the spindles, the said intermediate covers comprising for each section of spindles a pair of cover-members'having a conjoint working position edge to edge between the two rows or ranks of spindles, supported by their ends resting upon the said ledges of neighboring stands, and positioned endwise by means of the ribs of such stands, the said cover-members having diagonal or oblique marginal notches for occupancy by the spindles.

4. In a fly-frame having spindles in two rows or ranks, and cover-supporting stands .between sectional groups of spindles, of

cover-members in pairs closing the space intermediate the said rows or ranks, com osed of thin sheet-like material, and having ownturned longitudinal flanges, said paired cover-members supported by the end-portions of the edges of said flanges resting upon thestands, with the proximate edges of a pair contacting with each other.
